SPECIFICATION forming part of Letters Patent No. 321,859 dated July 7,1885.

Application filed January 5, 1885.

T0 aZZ whom it may concern:

Be it known that I, JAMES \V. SEE, of Ham ilton, Butler county, Ohio,have invented certain new and useful Improvements in Casters, of whichthe following is a specification.

This invention relates to furniture-casters, and it will be understoodfrom the following description, taken in connection with theaccompanying drawings, in which- 1 Figure 1 is a side elevation, partsection, of a furniture-caster embodying my improvement; Fig. 2, aperspective view of the movement, shown separately; and Fig. 3, adiametrical section through one of the disk-piles.

In the drawings, A represents the casterwheel 5 B, the horn; G, thestem; D, the socket for the stem; E, a box or cup at the lower end ofthe socket; F, vertical rivets arranged in circumferential seriesequidistant from the axis of the stem; G, piles of independent disksfitted to revolve loosely upon the rivets and bear peripherally againstthe stem; H, a pair of plates fitted to carry the rivets and form theframe parts for the movement,which thus forms an integral structureadapted to seat in the socket-cup; and I, Fig. 3, hubs struck up uponthe top and bottom disks of the pile.

The circumferential series of disk-piles form anti-friction wheels forthe stem-bearing. The disks G are accurately punched from sheet metal.They may be punched from the scrap formed in punching the plates H, andthey may be punched at the same punching-stroke with these plates,whereby the cost of the disks, both as to material and labor, ispractically reduced to zero. Each disk being free to revolve independentof its contiguous neighbor, the usual peripheral flattening is avoided,it being hardly possible for all of the disks of a pile to remainstationary and be subjected to the rubbing action of the spindle at onetime.

(Modem WVith solid anti-friction wheels it is common for a Wheel tostand still and have a fiat or concave place worn into its periphery bythe spindle, thus destroying the device.

I11 Figs. 1 and 2 the piles are formed of three disks, while in Fig. 3 Ishow a pile formed of four disks. The number employed is immaterial.

For extremely delicate casters it may be found desirable to provide thepiles with hubs, so as to avoid side friction far from the center of thedisks. Such hubs may be formed by striking up the outside disks, asclearly shown in Fig. 3.

Much that has been described is old and not original with me.

I also desire to state that skate-wheels and caster-wheels have beenformed of a number of layers of rawhide or the like permanently securedtogether by cement, nails, rivets, or clamping-flanges, so as to form anintegral structure.

I do not claim wheels so constructed as of my invention.

I claim as my invention- 1. In a caster, the anti-friction wheels formedby the combination of the metallic disks G into piles, each disk of apile being independent of its fellow disks, substantially as and for thepurpose set forth.

2. In a caster, the anti-friction rollers formed by the combination ofthe disks G into piles, the outer disk of each pile being provided withthe struck-up hub I, substantially as and for the purpose set forth.
